ORNAMENTING WOOD.

SPECIFICATION forming part of Letters Patent No. 314 392, dated March 24, 1885.

Application filed June 14, 1834. (Specimens) To all whom it may concern.-

Be it known that I, DAVID MOMULLAN, of the city and State of New York, have invented an Improvement in Ornamenting the Surface of Wood, of which the following is a specification.

Wood surfaces have heretofore been ornamented by the use of a tool or die that is either flat or cylindrical, said tool or die having ornamental designs cut into its surface and its surface ribbed or corrugated. These dies have been pressed into the surface of wood, the ribs or corrugations forming the background and the figures being left in relief. The ordinary color of the wood remains, and the ornamentation is only noticeable at a short distance, because the lights and shadows in the embossing are not heavy, as the embossing cannot be deep without injury to the wood.

My improvement consists in deadening and darkening the ribbed or corrugated background by the use of an ink or wood-stain, in order that the figures and ornamentation left in relief and of the natural color of the wood may be brought out and appear prominent and bold, although the background is countersunk but a small distance. This inking is accomplished by the use of an inking-roller running in contact with and delivering upon the surface of the corrugations uponthe cylindrical die the ink, which ink, in the operation of ornamenting the wood, is delivered upon and pressed into so much of the wood as forms the background. No ink enters the recessed portions of the die or is transferred upon the raised ornamental figures of the design.

In the drawings, Figure 1 is a section of the rollers made use of by me, and Fig. 2 represents the surface of wood that is ornamented by the roller.

I employ a die or embossing roller such as has before been known, wherein the surface is formed with sharp ribs or corrugations,- either parallel with or at an inclination to the axis of the roller, and wherein the leaves, vines, birds, or other ornamental designs to be brought out in relief are recessed into the roller. I employ a second roller, so that the wood to be ornamented can be passed between the two rollers, and I apply sufficient press ure to the die-roller to embed it the desired distance into the Wood. In connection .with these rollers I employ an inking rolleror rollers, and the surface of the die-roller receives printing or similar ink or wood-stain from said composition inking-roller upon the highest poltions of its surface or corrugations, and in the operation of ornamenting the wood such ink or woodstain is impressed into the wood portion forming the background of the design, and said background is made dark in consequence of the ink or stain. As the ink or stain does not enter the depressed portions of the roller and is not delivered upon the raised portions of the ornamental design, these parts are of the natural color of the wood, and are much lighter than the inked background, and stand out plainly and boldly in relief, and although the background may be depressed only about one-sixteenth of an inch the figures or ornaments stand out boldly in contrust with the background and appear much deeper than they actually are. I prefer to place the embossing or die roller D below the pressureroller E, and to apply the ink by the roller F, so as to avoid risk of injuring the ornamental surface by dust, chips, or other material falling on the same.

\Vood having an ornamental surface, as above described, and having the background darkened by ink or stain, is a new article of manufacture adapted to doors, casings, architectural ornaments, and furniture.

I claim as my invention- The method herein specified of ornamenting the surface of wood, consisting in pressing into the said wood a die having a corrugated surface, with ink upon the raised portions of the corrugations, and ornaments recessed into said surface, whereby ornaments are produced upon the surface of the wood in relief and of the natural color of the wood, while the background around such ornaments is corrugated and darkened by the ink, so as to render the design prominent, substantially as specified.

Signed by me this 12th day of June, A. D. 1884.
